There are many types of pollutants in food, and exposure involves multiple stages such as raw material, processing, transportation, storage, packaging, and sales. With the improvement of people's requirements for the healthy, nutritive and safe condiments, the pollutants in food have received more and more attention. Liquid chromatography-high resolution mass spectrometry (LC-HRMS) combines the separation ability of liquid chromatography with the advantages of high resolution mass spectrometry, such as wide mass range, fast scanning speed, and high sensitivity, making it an important means in the field of food safety analysis. This review summarized the technical characteristics of quadrupole-time of flight mass spectrometry and quadrupole-orbitrap mass spectrometry, as well as the research progress in the detection of pollutants in food using LC-HRMS technology over the past 5 years. The article focused on the application of LC-HRMS in the targeted and non-targeted determination of pesticides residues, veterinary drugs and their metabolites, food additives, illegal additives and mycotoxins, and prospected the development trend. Aiming to provide reference for the detection of pollutants in food in the future.
